[QUOTE="lcmlabforum, post: 77628, member: 3238"] One way to do this, is after you survey and design the framework, selected the path of insertion and removal, tripod the cast (or duplicate preferably) first. Then you lubricate/apply separating media around that one or 2 (hopefully not that many) surfaces before mixing up your Duralay or Pattern resin around the distal/mesial surfaces completely, cover the occl even for stability. Then you use your trusted milling machine to mill into that Duralay with a acrylic milling bur until you reach the stone part of the desired guideplane. Continue till you have the desired 2mm vertical surface, etc and created a resin jig for the DDS to 'perfectly' line up his burs to remove the part of the tooth that extends beyond your planned guideplane. I am not being sarcastic, but everything is only as good as you can do without creating it in wax on a cast restoration (or milled restoration) for a surveyed crown/retainer. If your DDS is a prosthodontist who is willing to show you, you might want to ask him/her how he/she want it done . . . Just my 2 cents' worth. LCM [/QUOTE]
